Biochemical engineer isolates a bacterial gene fragment

Reference no: EM13171797

A biochemical engineer isolates a bacterial gene fragment and dissolves a 19.6 mg sample of the material in enough water to make 37.9 mL of solution. The osmotic pressure of the solution is 0.340 torr at 25°C.

a) What is the molar mass of the gene fragment?
b) If the solution density is 0.997 g/mL, how large is the freezing point depression for this solution (Kf of water=1.86°C/m)?
